Feel like your hashtags are #boring and #irrelevant? One of the simplest ways to discover new hashtags for your content is by looking into the tags that you or your peers/competition are already using and letting Instagram show you additional hashtags that would work with your content.
Steps for finding relevant hashtags:
Open the Instagram app and go to any post (one of your own or someone else’s).
Select a hashtag (it will be preceded by the hash sign (#) and the text will be blue), and click on it.
This will take you to a landing page for the hashtag.
If the hashtag is considered “relevant” (or popular) Instagram will automatically display related hashtags at the top of the page, that you can swipe through left and right. (if a hashtag does not have a minimum amount of content tagged under it, this section will not appear.)
